**Very well done David!**

Thank you for working code! xD

I only regret that you write submitted psudocode. Hence, please accept my deepest (non)-regrets that I failed to read your code in detail for feedback purposes.

However, I did notice a lack of industry standard documentation. I suggest that you search for how to format file headers and function documentation comments for python files.

Keep it up!

The issue names Python files but no specific files or tests. Start by inspecting the repository's Python files and identify missing file headers and function documentation comments. Done means the relevant files have consistent industry-standard documentation.
